have different maximum and minimum remaining
length. Be careful not to use bolts beyond the specified
range which causes the tool damage.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Replacing carbon brushes (Fig. 16)
Remove and check the carbon brushes regularly. Replace
when they wear down to the limit mark. Keep the carbon
brushes clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only
identical carbon brushes.
Open the protector. Use a screwdriver to remove the
brush holder caps. Take out the worn carbon brushes,
insert the new ones and secure the brush holder caps.
(Fig. 17)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
